The mesodermal male genital system and the spermatophore of Zygaena trifolii (Insecta, Lepidoptera, Zygaenidae) have been studied histologically. Whereas the long unpaired duct, the ductus mesospermaticus, has been found to consist of at least six distinctly different regions, the tissues and secretions of the seminal vesicles and the accessory glands were found to be quite uniform. Several of the different regions are separated from each other by epithelial septa (constrictions). The external structure and the internal organization of the spermatophore are described. Based on histological comparisons, the correlation between the contents of the spermatophore and the different parts of the male system is given.
